“…A study by Kim et al. , comparing the prevalence of VUR in 338 patients after hypospadias repair, found a higher prevalence rate of 12% in patients aged <1 year than in healthy children (0.4–1.8%). This was similar to the rate reported in other studies .…”

“…Kim et al. showed that most VUR resolved or was downgraded in those with primary VUR detected at the time of hypospadias repair and that subsequent screening VCUG was most likely unnecessary. In the present study, the prevalence of VUR in those patients who underwent VCUG after hypospadias repair was 13/25, which is substantially higher than in the Kim et al.…”

E.W. and P.P. contributed equally to this manuscript Objective• To examine the development of recurrent urinary tract infections (UTIs) in boys who have undergone hypospadias repair. Materials and Methods• We retrospectively reviewed the records of all boys who had recurrent UTIs after primary or redo tubularized incised plate (TIP) or transverse island flap (TVIF) repairs, between 1998 and 2009. • Data on age, operating details, postoperative complications and imaging studies were collected.• We attempted to identify risk factors for recurrent UTIs after hypospadias repair. Results• During the study period, 43/2249 boys (1.91%) were diagnosed with recurrent UTIs after hypospadias repair. The boys' mean (range) age at repair was 14 (6-24) months and the median (range) follow-up was 6.5 (1.5-11) years.• Primary TIP and TVIF were performed in 47% (20/43) and 35% (15/43) of the boys, respectively. Redo surgeries were performed in 18% of the boys (8/43). The initial meatal location was proximal in all TVIF and redo repairs, and in one of the TIP repairs.• Postoperative voiding cysto-urethrography, ultrasonography and dimercapto-succinic acid (DMSA) scans were performed in 58% (25/43), 90% (39/43) and 19% (8/43) of the boys, respectively. Abnormalities were noted.• Of those boys who underwent a TVIF repair, urethral diverticula were seen in 47% (7/15) and urethral fistulae were also seen in 47% (7/15). Conversely, in those who had a TIP repair, an elevated PVR and vesico-ureteric reflux were more common; they were found in 40% (8/20) and 50% (10/20) of patients, respectively. Conclusions• The pathophysiology of recurrent UTI is multifactorial, but postoperative complications seem to vary with type of procedure.• Recurrent UTIs after hypospadias surgery should prompt a specific assessment for potentially functionally relevant and correctable anatomical abnormalities.

“… 1 , 2 , 3 An incision is made to reduce hydronephrosis, improve the renal function, reduce the risk of urinary tract infection, and prevent vesicoureteral reflux (VUR). 4 The endoscopic treatments of ureteroceles vary; however, the standard procedure is incision using a transurethral resection device. We herein report an adult case of bilateral ureterocele that was successfully treated by a half-loop transurethral resection technique.…”
